Making Sure You're Secure when Using Trusted Devices
Different Bluetooth® devices support different Bluetooth® standards and security
capabilities. There's a chance someone could keep your Xperia™ device unlocked by
imitating your Bluetooth® connection, even if your trusted device is no longer nearby.
Your device is not always able to determine whether your connection is secure from
someone trying to imitate it.
When your device can't determine that you're using a secure connection, you'll get a
notification on your Xperia™ device and may need to manually unlock it before the
trusted device can keep it unlocked.
Bluetooth® connectivity range can vary depending on factors like the model of your
device, the connected Bluetooth® device, and your environment. Depending on these
factors, Bluetooth® connections can work over distances of up to 325 feet (100 meters).
If someone takes your Xperia™ device while it's near a trusted device, they may be able
to access your Xperia™ device if the trusted device has unlocked it.
Connecting to Trusted Places
When the Trusted places feature is set up, the lockscreen security on your Xperia™
device gets disabled when you are in a designated trusted location. For this feature to
work, you must have an Internet connection (preferably over Wi-Fi®) and allow your
device to use your current location.
To set up trusted places, first make sure high-accuracy location mode or battery-saving
location mode is enabled on your device before you add home or custom locations.
The exact dimensions of a trusted location are an estimate and may extend beyond the
physical walls of your home or other area you have added as a trusted location. This feature
can keep your device unlocked within a radius of up to 260 feet (80 meters). Also, be aware
that location signals can be replicated or manipulated. Someone with access to specialized
equipment could unlock your device.
